Subject: [PATCH 02/10] sparc: Convert local_softirq_pending() to use per-cpu op
Date: Thu, 29 Mar 2018 04:26:57 +0200	[thread overview]
Message-ID: <1522290425-22844-3-git-send-email-frederic@kernel.org> (raw)
In-Reply-To: <1522290425-22844-1-git-send-email-frederic@kernel.org>

In order to consolidate and optimize generic softirq mask accesses, we
first need to convert architectures to use per-cpu operations when
possible.
